Hard Ferrite magnets are sintered permanent magnets composed of Barium or Strontium Ferrite. This class of magnets has good resistance to demagnetisation and corrosion, Due to their low cost, Ferrite magnets enjoy a very wide range of applications, from motors and loudspeakers to toys and crafts, occupy about 75% of the world market of constant magnets. we can supply you with both wet-pressed anisotropic and dry-pressed isotropic grades in all shapes and sizes.

Key Features of strong magnet

1.High intrinsic coercive force2.Available in simple shapes only due to manufacturing process3.Lower service temperature than alnico, greater than rare earth4.Lower energy product than alnico and rare earth magnetsProduction processFine Grinding—Magnetic field moulding—Sintering—Grinding—Untrasonic cleaning—Sorting—Packing—DeliveryPacking1. By Sea: They will be packed in a white box of pieces each, several boxes to a carton. (Detailed package quantity should be made upon the real products)2. By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.TransportationAll available shipping ways could be applied, by courier, air or sea, better to choose by sea.1. By Sea: If the GW is over 50kg, we advise ship by sea when you are not urgent for the goods as the charge of ocean way is cheaper than by air.P.S Appointed shipping company or our own forwarders all could be used in shipment.2. By Air: If the good below 30kg, we advise to ship by air as we QMET signed a long-term agreement with Express (DHL, TNT, FedEx) and the best discount we can provide to you.3. Full-way tracking the cargos for you before the goods arrivePayment1.For small amount, our usual way of payment is 100% T/T in advance, Western Union or Papal.2.For large amount, we also could accept 30% prepayment before production, 70% after scanning copy of Bill of loadingApplicationBuyer GuideIn order to quote you the best price of magnet quickly . please provide the following information:1. Magnet's size . grade . magnetic direction,quantity2. Attached the drawing if customized3. Any special packing or other requirementIf you have any questions,pls don't hesitate to contact us
